PBT engineering mapurasitiki, (polybutylene terephthalate), ine yakanakisa dhizaini mashandiro, ine mutengo wakaderera, uye ine yakanaka yekuumba kugadzirisa. Mumagetsi, midziyo yemagetsi, midziyo yemuchina, mota uye midziyo chaiyo nemimwe minda, yakashandiswa zvakanyanya.
Hunhu hwePBT yakagadziridzwa
(1) Yakanakisa michina zvivakwa, simba rakakura uye kuramba kuneta, yakanaka dimensional kugadzikana uye kudiki kunokambaira. Pasi pemamiriro ekushisa kwepamusoro, kushanda kunoshanduka zvishoma.
(2) Yakareruka murazvo wekudzoreredza, uye murazvo unodzoreredza une hukama hwakanaka, nyore kugadzira yakawedzera mhando uye maitiro emhando yemoto retardant giredhi, inogona kusangana nezvinodiwa zveUL94 V-0 giredhi. Yakave yakashandiswa zvakanyanya mumagetsi uye indasitiri yemagetsi.
(3) Kupisa kupisa, kuchembera kuramba, organic solvent kuramba. Iyo yakakwidziridzwa UL tembiricha index inochengetwa muhuwandu hwe120 ° C kusvika 140 ° C, uye ese ane yakanaka yekunze kuchembera kwenguva refu.
(4) Zvakanaka kugadzirisa kushanda. Zviri nyore kune yechipiri kugadzirisa uye kuumba kugadzirisa, nerubatsiro rwemichina yakajairika inogona kuve extrusion kuumba kana jekiseni kuumba; Iyo ine kukurumidza crystallization rate uye yakanaka fluidity, uye tembiricha yekuumbwa yakadzikira
Kugadziridza nzira yePBT
1. Kuvandudzwa kwekugadzirisa
MuPBT yakawedzera girazi fiber, girazi fiber uye PBT resin bonding simba rakanaka, muPBT resin yakawedzera imwe girasi fiber, kwete chete inogona kuchengetedza PBT resin kemikari inopikisa, kushandiswa uye zvimwe zvinobatsira zvepakutanga, asiwo zvinogona kuva ne kuwedzera kukuru mumichina yayo, uye kukunda iyo PBT resin notch senitivity.
2. Flame retardant shanduko
PBT icrystalline inonhuhwirira polyester, isina murazvo wemoto, inodzoreredza murazvo wayo UL94HB, chete mushure mekuwedzera kwemurazvo wemoto, inogona kusvika UL94V0.
Zvinowanzo shandiswa zvinodzoreredza moto zvine bromide, Sb2O3, phosphide uye chloride halogen flame retardants, senge yakanyanya gumi bromine biphenyl ether, yanga iri iyo huru PBT, inodzoreredza murazvo, asi nekuda kwekuchengetedzwa kwezvakatipoteredza, nyika dzeEurope dzakarambidza kwenguva refu kushandiswa, the mapato ari kutsvaga anotsiva, asi haana kuita zvakanaka kwave kunopfuura gumi bromine biphenyl ether inotsiva.
3. Kugadziriswa kwekubatanidza alloy
Chinangwa chikuru chePBT kusanganisa nemamwe mapolymer ndechekuvandudza iyo notched simba rekuita, kugadzirisa iyo warping deformation inokonzerwa nekuumba shrinkage, uye kugadzirisa kupisa kupisa.
Kusanganisa kunoshandiswa zvakanyanya kuigadzirisa kumba nekune dzimwe nyika. Mapolymers makuru akagadziridzwa anoshandiswa kusanganisa PBT iPC, PET, etc. Mhando iyi yezvigadzirwa zvinonyanya kushandiswa mumotokari, zvemagetsi uye maturusi emagetsi. Chiyero chegirazi fiber chakasiyana, uye munda wayo wekushandisa wakasiyanawo.
Kushandiswa kukuru kwePBT zvinhu
1. Zvishandiso zvemagetsi
Hapana fuse breaker, electromagnetic switch, drive back transformer, home appliance handle, connector, etc. PBT inowanzowedzerwa 30% girazi fiber kusanganiswa sekubatanidza, PBT inoshandiswa zvakanyanya nekuda kwe mechanical properties, solvent resistance, kuumba kushandiswa uye mutengo wakaderera.
2. Kupisa kupisa feni
Girazi fiber yakasimbiswa PBT inonyanya kushandiswa mukupisa kupisa feni, iyo yekupisa kupisa fan inoiswa mumushini kwenguva yakareba kuti ibatsire kupisa kupisa, iyo yemuviri midziyo yepurasitiki inodiwa ine kupisa kwekupisa, kupisa, kuvharidzira uye kusimba kwemagetsi, PBT ndiyo. kazhinji iri muchimiro che30% faibha inoiswa seyekupisa kupisa feni kunze kwefuremu uye fan blade coil shaft.
3. Zvikamu zvemagetsi
Girazi faibha yakasimbiswa PBT inoshandiswawo seshanduko, relay mukati mecoil shaft, kazhinji PBT pamwe nefiber 30% jekiseni kugadzira. Zvinhu zvinodiwa zvemuviri zvekoil shaft zvinosanganisira kuvharidzira, kupisa kupisa, kusungirirwa kwesimbi, fluidity uye simba, nezvimwewo zvinhu zvakakodzera ndeyeGLASS fiber yakasimbiswa PBT, GLASS FIBER yakasimbiswa PA6, GLASS FIBER yakasimbiswa PA66, nezvimwewo.
4. Automotivezvikamu
A. Zvikamu zvekunze: kunyanya bumper yemotokari (PC/PBT), mubato wegonhi, latisi yekona, injini inopisa gomba chivharo, motokari yemotokari yemotokari shell, fender, wire cover, wheel cover car transmission gear box, nezvimwewo.
B. Zvikamu zvemukati: kunyanya zvinosanganisira endoscope brace, wiper bracket uye control system valve;
C, mota dzemagetsi zvikamu: mota ignition coil twist chubhu uye akasiyana emagetsi ekubatanidza, nezvimwe.
Panguva imwecheteyo, inogona zvakare kuiswa kune yekuchaja pfuti ganda remagetsi matsva emotokari.
5. Mechanical midziyo
PBT zvinhu zvakare inoshandiswa zvakanyanya muvhidhiyo tepi rekodha bhandi drive shaft, chivharo chekombuta, mercury lampshade, chivharo chesimbi, zvikamu zvemuchina wekubikira uye nhamba huru yegiya, CAM, bhatani, imba yemagetsi yewachi, zvikamu zvekamera (ine kupisa, murazvo unodzoreredza zvinodiwa. )
